Increasingly, people are studying social and collaborative Web technologies for use in science (1, 2). However, issues such as privacy, confidentiality, and trust arise around the use of these technologies. Science is crucially based on knowing provenance— who produced what, how and where—and on the Web, trusting scientific information is becoming more difficult for both scientists and the general public. User-generated content, even from professionals, can be opinionated (both informed and uninformed), inaccurate, and deceiving. With an overwhelming amount of information of questionable origin and reliability, finding trusted information created by trusted people is the new challenge. The use of social trust relationships for this task is both practical and necessary as the Web evolves.
